What the comparison shows
Nearby hubs retain substantial overlap. Intercontinental pairs can have little or no shared 09:00–17:00 time, so teams may need rotating meeting windows.

How much of a standard 09:00–17:00 workday overlaps between major business hubs? This report compares two fixed dates so seasonal clock changes are visible instead of silently averaged away.

Working-hours overlap by city pair
The table counts 30-minute intervals when both cities are locally between 09:00 inclusive and 17:00 exclusive.
| City pair | 15 Jan 2026 | 29 Jul 2026 | Sample pattern |
|---|---|---|---|
| Cairo–London | 6 hours | 6 hours | Stable in sample |
| Cairo–Dubai | 6 hours | 7 hours | Seasonal difference |
| Riyadh–London | 5 hours | 6 hours | Seasonal difference |
| London–New York | 3 hours | 3 hours | Stable in sample |
| London–Singapore | 0 hours | 1 hours | Seasonal difference |
| Dubai–Singapore | 4 hours | 4 hours | Stable in sample |
| New York–Los Angeles | 5 hours | 5 hours | Stable in sample |
| São Paulo–London | 5 hours | 4 hours | Seasonal difference |
Why two dates?
One current offset can hide daylight-saving changes. January and July snapshots make seasonal differences visible without predicting future legislation.
